A known measuring device for issuing liquid fuel (Patent for a utility model of the Russian Federation No. 45120) consisting of a pump, an electric motor, a volume meter, a reading device and a dispensing tap. This device is characterized by the structural complexity of all elements, especially the volume meter. In addition, to these devices - fuel dispensers - there are certain requirements for the explosion protection of its constituent elements.

The closest analogue to the proposed device is a measuring system for filling liquids from storage tanks (Utility Model Patent of the Russian Federation No. 37710), which contains a pump with an electric motor, a filter, a flow sensor with a pulse shaper, a shutoff valve, a reading device with an indication, and a control controller.

The disadvantages of this system is that all the blocks and functional elements are not a single design, are tied to one specific tank and are mounted on the site in place, which implies the lack of a single configuration and the complexity of installation.

Also, the disadvantage of this device is the complex electronic control system for hydraulic units, which is functionally spaced into several blocks. This implies complex algorithms for the interaction between the control system and the terminal functional blocks, complex schemes for providing power to the installation.

The purpose of this utility model is to eliminate these shortcomings, increase mobility in the organization of points for dispensing liquids; creation of structural integrity; providing simplicity and accessibility of connection, setup and operation.

The specified result is achieved by the fact that the installation of the dispensing liquid contains a pump with an electric motor, a filter, a valve system, a liquid meter with an electronic signal converter, an electronic scoreboard that are installed in series with the flow.

Distinctive features of the claimed utility model is that:

1. A pump, with an electric motor, a filter, a liquid meter with an electronic signal converter and a valve system form a hydraulic system, and a pressure hose with a dispensing valve is inserted into it. The hydraulic system is located in the hydraulic unit and serves to measure and transport the fluid through the pipeline from the portable tank to the tank, refueling vehicle or other container. The pump is combined with an electric motor. The use of a single-phase electric motor makes it possible to simplify the design of the installation, ensuring its launch from the electronic display.

A safety valve is installed at the pump outlet, which opens at a certain pressure and directs fluid through the return pipe to the pump inlet, creating a safety system against pump overload with the shut-off valve closed.

A paddle fluid meter with an electronic signal converter is used to convert the fluid flow passing through the unit into a sequence of electrical pulses proportional to this volume.

The main line of the hydraulic system consists of: a shut-off valve that protects against the reverse movement of fluid during inflation of the dispensing sleeve; two-speed electromechanical valve; a dispensing sleeve with a dispensing tap and a flexible pipe that eliminates the transmission of vibration to the unit body and allows for quick connection to a portable tank. A two-speed solenoid valve serves to reduce the rate of fluid flow through the liquid meter on the last liter, the dose dispensed, and then completely shut off the flow at the time the dispensing is completed. A two-stage shutdown of the fluid flow allows to reduce the measurement error of the dispensed dose and to reduce the energy of water hammer in the pressure pipe. The dispensing valve has a shut-off valve and an elongated spout to reduce foaming.

A distributed type autonomous flexible electric heater with the possibility of turning it off in the warm season is also introduced into the hydraulic unit.

2. The electronic board, including the control board, display board, switching elements form an electronic system located in the information block.

Runtime control board based on an 8-bit microcontroller with a transformer power supply. The board contains elements of various physical interfaces. The control board is used to process commands received from the control system, control the start and stop of the installation, display and storage

information on the release of fluid, to configure the operating parameters and electronic correction of the fluid meter.

The display board is made on the basis of liquid crystal indicators (three lines), and allows you to display information about the price of the liquid, the current value of the amount of liquid dispensed and its value in the process of dispensing liquid

The electronic board contains a total metering unit, the information of which can be displayed.

The switching elements include: “Start-stop” button; electromechanical key to protect access to software; terminal box for switching wires.

The information block is located at the top of the unit. The exchange of information between the installation and the control device is carried out through the interface, the basic control device is the controller (console) control, working in a single protocol with the installation.

3. The hydraulic and information blocks are enclosed in a single housing and connected to a portable tank.

The dispensing fluid installation is a single housing consisting of: a base, a vertical strut, a cross bar and facing panels of the hydraulic and information blocks. The base is a load-bearing base; all elements of the housing are attached to it, providing easy assembly of the installation.

The portable tank is equipped with a suction line with a filter, a check valve and a low level sensor, which is connected to an electronic display. The intake line is made in the form of a flexible pipe with quick disconnect connections

The essence of the claimed installation of the dispensing fluid is illustrated by an example of its implementation and by drawings, where an embodiment is shown in accordance with the claimed technical solution.

The figure 1 presents a General view of the installation of the dispensing fluid.

The figure 2 shows the hydraulic installation of the transfer case.

The figure 3 presents a diagram of the electrical connections of the installation of the transfer case.

The general view of the installation (Fig. 1) shows the housing 1, the base 2, the transverse strip 3 with the terminal box 4, the facing and removable panels 5, the hydraulic unit 6, the pump combined with the engine 7, a flexible pipe to eliminate vibrations 8, a pressure hose 9 with a dispensing cock 10, an information block 11, a push-button post 12, a portable reservoir 13 with a low level sensor 14.

The hydraulic circuit of the hydraulic unit (Fig. 2) shows the elements of this circuit: a portable reservoir 13 with an inlet filter of the reservoir 15 and a check valve 16 located therein, a suction line 17, a check valve of the installation 18, a filter 19, a pump with an electric motor 7, and a safety valve 20, shutoff valve 21, fluid meter 22, two-speed solenoid valve 23, pressure hose 9 with a dispensing valve 10.

The electrical connection diagram of the information block (Fig. 3) shows: a pump with an electric motor 7; portable tank lower level sensor 14; liquid counter 22; two-speed solenoid valve 23; electronic board 24 with an indication board 25, an electric heater 26; start-stop button 27; electromechanical key 28; controller (console) 29.

The installation can work both in remote mode on command from the control system, and in stand-alone mode. The control system can be a controller (remote) control or a computer system operating on an interface in a single protocol with the installation.

After setting the dose from the control system (in remote mode), the unit is ready for dispensing fluid. By pressing the "Start-stop" button, the electronic display (Fig.3 pos.24) generates self-test signals, and then sets the display indication to zero; opens a two-speed solenoid valve (Fig.2 pos.22) and turns on the pump motor (Fig.2 pos.7) installation.

Under the influence of the fluid flow, the fluid meter with an electronic signal converter (Fig.3 pos.22) generates a sequence of electrical pulses, the number of which is proportional to the volume of the transmitted fluid. The sequence of electrical pulses is fed to an electronic display (Fig.3 pos.24) for further processing. The liquid from the liquid meter (FIG. 2, pos. 22) through a two-speed solenoid valve (FIG. 2, pos. 23) and the dispensing valve (FIG. 2, pos. 10) is supplied.

The electronic scoreboard (Fig.3 pos.24), having received information from the liquid meter (Fig.3 pos.22), processes it, compares it with information about the set dose and price received from the control system, and displays the current value on the indicators of one-time accounting the amount of liquid dispensed and its value. Upon reaching the set value before the end of the dose, the electronic display (Fig.3 pos.24) includes a two-speed solenoid valve (Fig.3 pos.23) at a reduced flow rate, and at the end of the dose it turns off the pump motor (Fig.3 pos.7) and closes valve (Fig.3 pos.23). At the same time, data on the release of liquid, as well as data on the total metering, are transmitted to the control system (Fig. 3, pos. 29).

The unit stops the flow of fluid under the following conditions:

1. The end of a given dose.

2. Pressing the “Start-stop” button again.

3. Receiving the “Stop” command from the control system.

4. Receiving a signal from the tank low level sensor.

5. Emergency power off.

An electronic display allows electronic alignment and adjustment of installation parameters. The settings can be carried out from a push-button post (Fig. 1, pos. 12) or remotely by the control system.

Electronic adjustment allows a one-time change in the dose of delivery within ± 0.5 liters. Moreover, access to changing metrological parameters is protected by software (password for access to software) and hardware (electromechanical key to protect access to software) in accordance with the requirements of the international organization of legal metrology. The method of conducting electronic adjustment consists in introducing the actually dispensed dose into the scoreboard, after which the scoreboard calculates and remembers the correction coefficients issued by the volume of the liquid meter.

The electronic board has the function of an electronic node for the total metering of the fluid dispensed. This total counter is cumulative, indelible. Viewing total counters can be carried out both remotely and autonomously using the button post of the electronic scoreboard.

During operation, the electronic display through the low level sensor monitors the liquid level in the portable tank and when it is reduced to the set limit, it stops the installation with information displayed on the display. This provides control over the formation of an “air plug” in the pipeline, while the non-return valve of the intake line (FIG. 2, pos. 16) prevents the liquid from flowing into the tank. The portable tank is connected using quick-disconnect couplings on a flexible connection, which makes it possible to quickly replace an empty tank with a full one in operation.

The installation heating system includes a flexible plastic electric heater (Fig. 3, pos. 26) of a distributed type, which is connected through a separate switch to exclude its operation in the warm season.
